No, you said "when your xdg list gets huge, apps should just use xdg out of the box". But the link you shared shows only 4 lines in your xdg list. 4 lines is hardly huge.
Why should I have to maintain a list of applications that don't conform to the standard? I tried to, and the list keeps growing. I'm done screwing around with it, I don't care how cluttered my homedir gets anymore.
